Interstate AGM vs NOCO Lithium batteries for 08 GTI

[cveldhouse]

Hey guys, I need new batteries for my 2 2008 Seadoo GTI 130s. I'm debating between a Lithium battery from NOCO or a AGM battery from interstate. Both are around the same price in my area and ive heard really good things about the lithium batteries besides the reserve capacity. Is there anything I should be aware of before buying?

I've never used a lithium battery, but this video might provide some info to help you decide.

Per the owners and service manuals jumping a Seadoo with the battery installed in the ski is a very bad idea. I guess in an emergency and you carry a jump pack with you, but your probably more likely to fry the ECM jumping the ski than ever needing a jump in the first place with a good AGM battery. Be aware also that if you have a parasite draw on a lead acid/AGM and completely drain it of voltage your not going to be able to jump it with a jump pack without the override also. If I was fishing routinely 20 miles offshore pretty sure I would install a dual battery system like most off shore boats have. Also be aware that manually jumping a lithium ion battery that is in a low voltage cutoff condition set by the BMS is very dangerous and a really good way to start a fire and burn up your ski.
